Product Description

 

Product Description

Composite geomembrane has the characteristics of high strength, good elongation, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, and good anti-seepage performance. Due to the use of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments. Commonly used for anti-seepage treatment in embankment and channel engineering. Composite geomembrane has the following advantages
 

(1) High anti-seepage coefficient: Composite geomembrane has an unparalleled anti-seepage effect compared to ordinary waterproof materials, with high-strength tensile mechanical properties. Its excellent elasticity and deformation ability make it very suitable for expansion or contraction base surfaces.
(2) Chemical stability: Composite geomembranes have excellent chemical stability and are widely used in wastewater treatment, chemical reaction tanks, and landfill sites.
(3) Anti aging performance: the composite geomembrane has anti-aging, anti ultraviolet, anti decomposition capabilities, and can be used naked. The service life of the material can reach 50~70 years, providing good materials for environmental seepage prevention to ensure resistance to plant roots.
(4) High mechanical strength: Composite geomembrane has good mechanical strength, with a tensile strength of 28MP and a fracture elongation of 700%.

(5) Low cost and high efficiency: The composite geotextile membrane adopts new technology to improve the anti-seepage effect, but the production process is more scientific and fast, so the product cost is actually lower than traditional waterproof materials. According to actual calculations, using composite geomembranes in general engineering can save costs by about 50%
(6) Fast construction speed: Composite geomembranes have high flexibility, with various specifications and laying forms to meet different engineering anti-seepage requirements. They use hot melt welding, with high weld strength and convenient and fast construction.
(7) Environmental and non-toxic: The materials used in the composite geomembrane are all non-toxic and environmentally friendly. The principle of anti-seepage is ordinary physical changes that do not produce any harmful substances, making it the best choice for environmental protection, aquaculture, and drinking water tanks.
Compared to materials such as masonry and concrete, composite geomembranes greatly reduce the cost of engineering. So the project uses composite geomembrane for anti-seepage.

Construction precautions

Preparation before laying:
1. Foundation treatment: Clean the surface of the geotextile membrane, ensuring that the substrate is flat, the soil is solid, and there are no unevenness, cracks, sharp objects, stones, iron wires, wooden sticks, etc. Within the anti-seepage range, the grass and tree roots should be removed, and weed control agents should be sprayed.
On the contact surface with the membrane, a layer of sand or clay with small particle size should be laid as a protective layer, and the thickness of the protective layer should not be less than 30 cm.
 

Laying method:
1. Lay in a certain direction, but do not pull too tightly. Leave a certain amount of expansion and contraction to adapt to the deformation of the substrate.
2. A PE film with a certain width reserved on both sides of the geotextile and a non adhesive layer of PET fabric (i.e. edge throwing) should be laid. When laying, the direction of each unit of geotextile should be adjusted to facilitate the welding of the two unit geotextiles
3. After laying the geomembrane, it should be pressed with a sandbag to prevent wind and sand from affecting the welding of the edge of the geomembrane in the next step
4. Geomembrane welding. Joint treatment is a key construction procedure, usually using hot welding method. The surface of the PE film is heated to melt, and then fused into a whole through pressure
5. For the laid geomembrane, the edge joints must be free of oil, water, dust, etc
6. Before welding, adjust the two sides of the PE single film at the joint to overlap a certain width, which is generally 6-8 cm and flat without wrinkles
7. Use a dedicated welding machine for welding
